I apologize I am doing a poor job of describing the issue. I really appreciate that I am getting replies and attempted to help. 

The issue is that the list will not clear of old entries. The company files that were on the old server will not disappear from the list. I go to edit and check them all and remove them from the list. But when I open the company file from the new location and close it, the old list repopulates itself and will not add the company files from the new server. I can connect to the new files and open them with no issues.

I cannot save the new locations to the Company file list and I cannot delete the previous entries in the list. When I try to delete them, the list repopulates with old entries. \

Is there a file or location I can find to manually edit this list outside of Quickbooks? Can I use file explorer and delete the file and force quickbooks to build a new list file?
